About this 3D model
Summary Shuttlecocks tend to dry out in storage rolls, which significantly reduces their lifespan. This lid with moist hydro-ball elements provides a constant release of moisture, thus preventing premature drying and the associated reduction in the balls' durability. About 10 hydro beads (Pearl.de) are pressed into the upper hole. The entire lid is then immersed in water for a few hours so that the beads can absorb the water. After that, the lid can be placed on the badminton roll, and the shuttlecocks will be kept in a humid roll environment for several weeks, which extends their lifespan. The opening for the hydro balls is 3.7 mm. Therefore, no significantly larger balls should be bought. These balls should work.
